ALARM-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 451,639, dated May 5,1891.

Application filed March 17, 1890. Serial No. 344,158. (No model.)

To all w/tom t may concern.-

Beit known that I, MICHAEL A. OD ONN ELL, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inAlarm-Signals; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to alarm-signals.

Heretofore in cities having the patrol box and wagon system it has beennecessary for an officer after making an arrest to take his prisoner tothe nearest patrol-box, and while holding said prisoner with one handinsert his other hand in his pocket for the patrolbox key, with which toopen the patrol-box door and'send in the alarm-call, as under thepresent system an alarm-call cannot be turned in until after thepatrol-boX door has been opened. This is objectionable, and oftenattended with danger, as in numerous instances the prisoner hasassaulted the officer and made his escape while the officer was in theact of inserting his hand in his pocket for his patrol-box key. Thisdifficulty I propose to obviate; and the object of my invention is toconstruct a device to be attached to the outside of the patrol-box thatWill,in connection with a policemans club or baton, enable the officerto turn in the alarm-call without opening the patrol-box door; and tothis end the nature of my invention consists of constructions andcombinations,all as will behereinafter described in the specification,and particularly pointed out in the claims, referings, in which-- Figurel is a sectional View of a patrol-box having my device attached; Fig. 2,a sectional view of a policemans club or baton having an alarm signal orwhistle in its handle, by which my device is operated; and Fig. 3, amodification.

A represents the patrol-box, having located therein the usual lockedtelephone-box B, containing a telephone transmitter h and receiver h',also the ordinary mechanical call device C, with its signal-giving leverD, and a battery-box E, containing cells e for the telephone. To thehook d ou the end of the signal-giving lever D is attached awire F,which passes downwardly and around a roller f, secured tothe battery-boxE,then upwardly and connected to a projection or toe g on the end of ashaft G, which is secured in the side of the patrol-box A. The outer endg of this shaft G projects through a countersunk portion a of thepatrol-box A, and is of the same configuration as the mouth h of awhistle H, inserted in the upper end or handle of the policemans club orbaton I, so that the whistle-mouth can be fitted over said outer end gand made to act as a key or wrench to turn the shaft G, which in turn,through the medium of the wire F, operates the signal-giving lever D tosend iu analarm-call at the policestation K.

In cities where alarm whistles or signals of different configurationfrom that shown in the drawings are in use the outer end g of shaft Gwould have to be changed accordingly. not fit over the end g of theshaft G.

The operation is as follows: Vhen an officer has made an arrest ordesires to call the patrol-wagon, he inserts the handle end of his clubor baton in the countersunk portion a of the patrol-box A,` which issufficiently large to allow the handle to enter, and the mouth 7l.,acting as a key or wrench, is fitted over the outer end g of the shaftG. A halfrevolution of the club is then made, which. causes theprojection or toe g on the end of shaft G to be raised, thus tighteningthe wire F and pulling down the signal-giving lever D and sounding thealarm-call at the station K.

In the drawings I have shown an ordinary mechanical call device with mydevice attached to its signaling-lever; but I lay no claim thereto, asit is obvious that my device can be attached to any form of call device.It is also obvious that instead of the mechanical call device and itssignal-giving lever and wire connection an ordinary electric pushbuttonsignaling device M, having its wire m running through the telephone-boxB to the station K, as shown more plainly in Fig. 3, can be attached tothe inside of the patrolbox in such position that the projection g onOtherwise the whistle-mouth would IOO the shaft G when revolved willpush theliulzton in and complete the circuit, as in ordinarypush-buttons, and ring an alarm al: slation K.

That I claim isl. In an alarm-signal, the combination of a club or batonhaving a signal inserted in iis handle, and a signahoperating shaft of apatrol-box operated by the month ol. said signal, as set forth.

2. In an alarm-signaling device, the combination of a patrol-box, asig11al-transmitt'ing device with its pull in said patroldnox, a shaftsecured in the outside Wall of said patrol-box, mechanism controlled bysaid shaft for operating the pull, and a policemans club having in itshandle a cavity which acts as a key to operate said shaft',substantiallyas described.
